please explain your answers

3. Circle the stronger base in each pair. (0.2 pts ea = 2,0 pts) a. (CH3) COK vs. CH3OK b. HCECNa vs. CH3CH2ONa c. NaNH2 vs. HCECNa d. NacN vs. NaI e. NaHCO3 vs. NaOH f. NaOH vs. CoH5CO2Na g. C.H.COŻNa vs. CoHsONa h. CH3CO2Na vs. CHEONa u dotos i. CH3ONa vs. Nah j. NH3 vs. CH3CO2Na

Answer 1

a) (CH3)3OK is stronger base because of +I effect of three CH3 groups, electron density on oxygen increases thus, basicity increases.

b) HC$\equiv$CNa is stronger base because negative charge on carbon is less stabilized as compared to negative charge on oxygen in CH3CH2ONa.

c) NaNH2 is strong base than HC$\equiv$CNa because NH3 is weakly acidic and Alkyne is strong acid.

d) NaCN is strong base because HCN us weakly acidic as compared to HI.
